Your Patient Took Biology Many Years Ago

Your patient took biology many years ago. You remind her of the structure of DNA and RNA. Which statement is NOT correct?

A) DNA is usually a double-stranded, helical structure composed of nucleotides, each of which contains a sugar, a phosphate group, and a nucleobase (A, T, C or
B) The two strands of DNA are complementary and are held together by hydrogen bonds between the nucleobases.
C) RNA is a single-stranded molecule composed of nucleotides that contain the nucleobases adenine, thymine, uracil, or cytosine.
D) RNA nucleotides contain the 5-C sugar ribose while DNA nucleotides contain the 5-C sugar deoxyribose.
E) A single linear strand of DNA will always have a 5′PO4 at one end and a 3′OH at the other, referred to as the 5′ end (5 prime end) and the 3′ end (3 prime end) respectively.
